What is Compact Flash ?
CompactFlash (43W x 36H x 3.3D (mm)) is a NAND based flash memory storage device. CompactFlash does not require a battery to retain data. The cards have a 50 pin interface and comply with the PC Card ATA specification.
CompactFlash cards are solid-state hard disks, rugged, reliable and used in a variety of applications including PDA's, digital cameras and notebooks. The cards are made to operate with dual voltages (3.3 & 5V).
What does 100X, 300x and 1000X mean when referring to the speed of flash memory devices/cards ?
This is a speed measuring system adopted from the CD ROM industry. A 20X card is not 20 times faster than a standard card, which would be say 6X. It is in fact 2.5 times faster (1.2MB/s V 3.0MB/s). Actual speed results depend on the device.
Minimum Sustained Write Speed (1X = 150KB/sec).
What is UHS-I?
"UHS-1" or more accurately "UHS-I" stands for "Ultra High Speed" - 1 and is a speed class for SDHC and SXDC memory cards.
UHS-I is the fastest category of card available today with a bus interface speed of up to 104 MB/s.
SDHC UHS-I cards will work in any SDHC compatible device at lower speeds, but to take advantage of the UHS-I speed, a UHS-I compatible device is essential.
